Design and Performance

The behavior of a Message Queue application depends on many factors:
client design, connection configuration, broker configuration, broker tuning,
and resource management. Some of these are the responsibility of the application
developer; others are the concern of the Message Queue administrator.

In the best of possible worlds the developer should be aware of how
the Message Queue service can support and scale the application design, and
the administrator should be aware of the application's design goals when it
comes time to tune the application. Messaging behavior can be optimized through
redesign as well as through careful monitoring and tuning. Thus, a key aspect
of creating a good Message Queue application is for the developer and the
administrator to understand what can be realized at each stage of the application
life cycle and to share information about desired and observed behavior.
